WiFi Analyzer iOS

The WiFi Analyzer iOS tool passively scans the local radio environment to enumerate nearby WiFi networks, capturing beacon frames and management data from advertisements. It reports per-network metrics such as signal strength (RSSI), network type (2.4/5 GHz), channel, security (Open/WPA2/WPA3), and basic capabilities. The goal is to provide engineers, IT staff, and power users with a clear view of network conditions without connecting to any network, ensuring privacy and security.
Conceptually, the tool aggregates short-term measurements into per-SSID records and computes channel occupancy and interference indicators. It identifies which channels are congested, detects overlapping networks, and suggests viable alternatives. The analysis is privacy-preserving and passive, avoiding any credential access or traffic decryption.
Among the primary users are home users troubleshooting slow WiFi, small office IT staff planning deployments, and field technicians performing quick site surveys. The tool's value lies in turning raw beacon data into actionable recommendations, such as selecting a less congested channel or locating coverage gaps. Advanced users can export logs for external analytics.
Core features include live RSSI readings, SSID discovery (including hidden networks if permitted), per-channel utilization, simple interference scoring, and data export in CSV/JSON formats. The tool adheres to IEEE 802.11 standards and reports units in dBm and percent. It does not connect to networks, capture payloads, or compromise privacy.
